Fibonacci is Not a Pizza Topping - Redux

by Andrew Davis

What does a nautilus and the seeds of a sunflower have in common?  Their structural arrangement follows the Fibonacci sequence of numbers. Andrew revisits his superb article from April 2020 on the golden ratio with emphasis on the Fibonacci Series.

The golden ratio is a proportion or scale factor when measured against another dimension (think length versus width).  The golden ratio has been used as an aesthetic feature since Euclid discovered it around 300 B.C.E.  It was used by Vitruvius, a Roman architect and author, whose treatise called De Architectura inspired others including Leonardo da Vinci, a devotee of Fibonacci, to draw the Vitruvian Man.  Even the design of the Mona Lisa uses Fibonacci's Golden Spiral, which Andrew formulates in his article.

The golden ratio, like pi, is an irrational number so it's rounded to 1.618.  But it provides utmost rationality, that is, aesthetic found in nature and used as a design rule for architects, artists, builders, and woodworkers.  Treat yourself - not to pizza - but to an entertaining read of Fibonacci is Not a Pizza Topping - Redux.
